• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) xanh - hang ban cua dang cong van ((luan ban) OR (luan bang))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) OR (hoc thieu)) xanh - hang ban cua dang cong van ((luan ban) or (luan bang))~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) OR (hoc thieu)) xanh - hang ban cua dang cong van ((luan ban) or (luan bang))*.
